Cell data is way overpriced particularly when you're also paying for broadband on cabel or DSL. With my tablet I decided on a compromise and got a Boingo WiFi account for $7.95 per month. That gives me Starbucks, McDonalds, many hotels and major airports. Not anywhere but still always close by for me. There was some mention of gmail. I find using the internal mail client, modest, and IMAP access to gmail provides a more responsive mail experience.
